CNN political analyst Kirsten Powers hit back at former Donald Trump campaign adviser Jason Miller on the news network Tuesday night, after Miller used the term “hysterical” to describe Sen. Kamala Harris’ (D-CA) questioning of Attorney General Jeff Sessions during a Senate Intelligence Committee hearing.

“Can I just go back to something that Jason said? How was Sen. Harris ‘hysterical?’ I don’t really understand that. I mean, she was asking some tough questions,” Powers said.

“I believe this is the second hearing in a row with completely partisan screed,” answered Miller. Pushed by Powers on how that would mean Harris was “hysterical,” Miller added, “from my perspective … it didn’t seem like there was any effort to try to get to a real question or get to the bottom of it. She was purely out there to shout down [Sessions].”

After Powers responded that Harris was “dogged” in questioning Sessions, but so too was Sen. Ron Wyden (D-OR), Miller said, “I think she was hysterical. I don’t think that Sen. Wyden was really trying to get to the bottom of answers either. I think he was trying to drive a partisan [attack].”

“But he wasn’t hysterical and she was,” Powers replied. “Okay, I just wanted to clear that up. Got it.”

Miller repeated that he felt Harris was trying to “shout down” Sessions, which drew a further retort from Powers. “She didn’t shout, actually, but even if she did, I’m just saying that they both were asking a lot of tough questions and I think calling her hysterical is probably a little gendered thing to say,” Powers said.
